MiniWarden INSTALLATION
Mounting MiniWarden
Turn off any heaters, pool or spa circulation systems, chemical feed pumps or any related shut-off valves
or equipment and relieve pressure from the filtration system. Find a suitable mounting location near a
120/240 VAC power source that meets the following criteria:
●
Facilitates a combined (influent & effluent) maximum tubing run of 30’.
●
Do not mount controller above electrical sources or electrical equipment.
●
At least 10’ away from any pool, spa or body of water and not accessible to the public.
●
Away from corrosive materials and physical hazards.
●
Not in direct sunlight or directly above or near any heat source.
●
For 220 VAC, ability to hard wire with GFCI (ground fault circuit interrupter) protection.
Securely mount controller or the optional controller backboard vertically on the wall using supplied screws
or appropriate fasteners for the wall construction. Never mount MiniWarden horizontally.
Flow Cell To Circulation Plumbing
There are many ways to connect the flow cell tubing to the circulation plumbing. Successful flow cell
installation requires a pressure differential. One way to install is to make sure the input source to the flow
cell is well upstream from any chemical injection point (C Below). The Flow cell input and output points
before and after the filter provide the greatest pressure differential (see below). MiniWarden is equipped
with a strainer to filter out any debris from the unfiltered water. Periodically check and clean the strainer.
However, the flow cell input and output can also be installed before and after the heater if enough pressure
differential is available to create adequate flow through the flow cell.
●
Flow Cell Input: Drill & tap a connection point in the circulation system at a location just up-stream
from the filter (A - Below). Install tubing connector and run tubing to the input side of the flow cell.
●
Flow Cell Output: Drill & tap a connection point in the circulation system at a location with reduced
pressure just after the filter (B - Below). Install tubing connector and run tubing to the output side of
the flow cell.
CAUTION
: Maximum pressure across the sensors should be 10 PSI (pressure gauge may be required).
Always expose the sensors to positive pressure. Prevent exposing the sensors to negative pressure or a
vacuum by connecting the flow cell output tubing to the suction side of the pump as the vacuum may suck
the sensor gel from the sensors rendering the sensors inoperable in a very short period of time.
